Parents are always best placed to decide if a child is not well enough to attend nursery. Common colds and coughs are not a problem, apart from if the child has a high temperature with it, in which case they should stay at home until the temperature goes down without medication. There is a full list of potential illnesses and the amount of time children should be kept away from nursery, but the most common are as follows.
Diarrhoea or vomiting – 48 hours or until toileting returns to normal
Temperature above 38 degrees – 24 hours or until temperature returns to normal without the need for medication.
Conguntivitus – 24 hours after drops have been administered
